“…Pre-sowing tillage with a field cultivator induced a greater increase in WOR yields than conventional plowing (3.5 vs. 3.0 Mg ha −1 ). Strip-till is becoming increasingly popular in agricultural production, in particular in large commercial farms [26,54,55]. Shah et al [19] demonstrated that WOR yields were around 4% higher in strip-till than in low-till systems.…”

The aim of this study was to analyze agronomic management in the production of winter oilseed rape (WOR) in different tillage systems. The field experiment (Poland, 2016–2019) had a 35–1 fractional factorial design with two replications, where five fixed factors were tested at three levels. The experimental factors were as follows. A—tillage: (A0) strip-till, (A1) low-till, (A2) conventional tillage; B—weed control: (B0) pre-emergent, (B1) foliar, (B2) sequential; C—growth regulation: (C0) none, (C1) in fall, (C2)—in fall and spring; D—rate of spring nitrogen (N) fertilizer: (D0) 160, (D1) 200, (D2) 240 kg ha−1; E—rate of spring sulfur (S) fertilizer: (E0) 0, (E1) 40, (E2) 80 kg ha−1. Seed yields were the highest in the strip-till system (5.95 Mg ha−1). The effectiveness of weed control methods varied across different tillage systems. Foliar herbicides exerted the highest yield-forming effect in the strip-till system, pre-emergent and sequential herbicides were most effective in the low-till system, and pre-emergent herbicides were most effective in the conventional tillage system. Seed yields increased up to the N rate of 200 kg ha−1. The highest N rate of 240 kg ha−1 was justified only when S was applied in spring. Sulfur significantly increased seed yields (by 17%). The results of the study indicate that low-till and strip-till systems can be viable alternatives to the conventional tillage system in WOR production.

“…The dominant system for crop establishment in this region is plough-based tillage (Forristal and Murphy, 2009). While the adoption of non-inversion crop establishment systems has been low (Soane et al, 2012), interest has recently increased mainly to reduce escalating production costs (Forristal and Murphy, 2009), and these systems are primarily used to establish winter cereals (Brennan et al, 2015), but also spring cereals (Brennan et al, 2014) and noncereal break crops, including oilseed rape and beans (Byrne et al, 2022). Other reasons for interest in non-inversion tillage systems in this region include: labour shortage (Bijttebier et al, 2018), high work rates (Fortune et al, 2005), strong promotion by farmer-led organisations like BASE Ireland (Biodiversity, Agriculture, Soil and Environment) (BASE Ireland, 2018), the EU's mandatory crop diversification requirements of the Common Agricultural Policy (i.e.…”

The challenges of grass-weed control in a mild Atlantic climate, added to by the use of non-inversion tillage and limited herbicide options necessitated on-farm knowledge acquisition on grass weeds in Ireland. We surveyed 103 farms from 2020 to 2021 of which, 62 were plough-based and 41 non-inversion tillage. The survey comprised a questionnaire to determine grower demographics, grass-weed challenges, and the adoption of integrated grass-weed control methods (IWM); a grid-square assessment of key grass weeds encountered in one or more cereal fields in both years using weed scores from 0 (absent) to 10 (total weed cover); with samples collected for herbicide-resistance testing. Across the 103 farms, Bromus spp., (62%) and Avena fatua (56%) were the most prevalent but with moderate resistance (8% acetolactate synthase (ALS)-resistant Bromus, 10% acetyl-CoA carboxylase (ACCase)-resistant A. fatua); Lolium multiflorum (13%) and Alopecurus myosuroides (16%) were found on fewer farms but with higher resistance levels (56% ACCase and/or ALS-resistant L. multiflorum, 43% ACCase/ALS-resistant A. myosuroides). Of those who adopted non-inversion tillage, a higher proportion of growers practiced crop rotation (88% cereal/non-cereal break or 83% alternate spring/winter-sown) and used cover crops (71%) than those ploughing (52-66% crop rotation or 19% cover crops), but herbicide use was similar in both systems. Despite higher levels of IWM practices, non-inversion tillage farms had higher weed scores (2.2 ± 0.2 or 3.8 ± 0.7) of B. sterilis and L. multiflorum than ploughing (1.2 ± 0.2 or 2.0 ± 0.7). Considering the complex resistance profile of high resistance-risk species, there is a need for urgent determination of and adoption of effective IWM across systems, specifically, non-inversion tillage. Most of the growers were aware of herbicide-resistant grass weeds (>80%) and most (>90%) used IWM practices (4 or more) to some extent. In our survey, non-inversion tillage farms tended to have younger growers with more formal education and larger farms. This is the first multi-component survey in Ireland establishing long-term monitoring of grass-weed challenges, grower characteristics and IWM practices.

BACKGROUND Understanding of mechanisms that underpin high‐yielding cropping systems is essential for optimizing management practices. Currently, the contribution of plant traits such as leaf area, chlorophyll content and intercepted photosynthetically active radiation (PARi) to yield and nitrogen use efficiency (NUE) are not fully understood. In addition, the understanding of how canopy traits are affected by nitrogen (N) management practices is unclear. The present study aimed to determine the effect of amendment with controlled release urea (CR), common urea or no urea on NUE and plant eco‐physiological characteristics in a 2‐year field study in a double rice cropping system. RESULTS Regulation of N release through amendment with CR significantly increased grain yield, NUE and leaf morpho‐physiological attributes. CR coupled with common urea (at comparable total N rates) increased leaf area index (LAI), relative chlorophyll content index (CCI) and PARi, leading to higher grain yield and NUE (increased 24.4% and 25.3% in early and late rice, respectively) compared to local farming practice. Structural equation model (SEM) analysis showed that differences in N application, between CR and common urea, directly accounted for differences observed in soil nutrient, PARi and NUE rather than yield components. Additionally, compared to traditional yield determinants, LAI and PARi (between booting and filling stage) are capable of predicting and explaining grain yield by 0.69 and 0.92 of R2 in early and late rice, respectively. CONCLUSION Leaf morpho‐physiological traits are important for developing N management practices to increase NUE and improve food security for paddy agriculture in southern China. © 2022 Society of Chemical Industry.
